该MD在评论里发了一个dropbox文档,介绍了试剂盒,由一家杭州的公司开发并在2月、3月做过临床试验: FaSTEP (by Assure Tech) Assure Tech. (Hangzhou) Co., Ltd., the manufacturer of FaSTEP performed clinical trials at two sites in China from February 2020 to March 2020. These clinical trials were aimed to evaluate the performance of the COVID-19 IgG/IgM Rapid Test Device (Whole Blood/Serum/Plasma) against known patient PCR results: IgM Testing • 74/79 PCR+ patients who were also symptomatic also had a positive rapid test for IgM (93.7% sensitivity) • 225/227 PCR (-) patients had a negative rapid test (Specificity 99.1%) IgG Testing • 82/83 patients who had recovered from the disease were positive for IgG (Sensitivity 98.8%) • 224/227 PCR (-) patients had a negative rapid test (Specificity 98.7%)
有一定可能会检出季节流行的其它冠状病毒 · Manufacturers of these tests state the possibility of cross reactivity with seasonal Coronaviridae
赞同。非常有必要。

赞角度!特别去年底到现在有flu症状的人。。。
甩就甩吧,墙外的人大多都有数
还有一种可能是开始都是轻症,后来不知怎么小变异了一下,就出现大量重症了。其实起源真的很难讲清,大量的谜团。
一月份得的病症状类似COVID-19感染,之后有COVID-19病毒抗体,那么他的猜测是最合理的。这是两个相关证据,逻辑完全没有问题。和吃饭 抗体完全不同。
得瑟啥,说不定你是无症状携带者,光传染别人了
1月1日和1月31日都是1月,地点也没说明,信息不完全
IgG是远期感染的指标,近期感染是IgM, 这个医生说得对。
这测试准确率多少?
痊愈这么长时间核酸早就阴性了
我们州长就是这么说的,但是不知道这个测试有没有快筛。我记得没错的话IgG应该只要有个tag就可检测到,以前在lab好像有各种IgG的测试kit
免疫学渣路过,赞一下图
对的
目前确诊病例的测试三分之一是假阴
antibody测试不知准不准
不过按理说这个是amplified的,所以可能更sensitive
所以会有false positive?
